3 Claims.

Thi invention relates to totalizing and recording devices, and among other objects aims to adapt an adding machine for certain recordin functions which do not influence totalization.

The invention may be readily understood by reference to one embodiment thereof shown in the accompanying drawings.

Fig. 9 illustrates a sample piece of record tape; and

Fig. 10 is a sectional elevation of a detail of the shifting mechanism, taken on the plane l0-lli of Fig. 6.

According to the present invention, it is possible to utilize surplus or idle denominational orders and the printing mechanism associated therewith for recording purposes, without carrying the same into the totalizing or accumulating mechanism. For example, if, in the normal use of an adding machine whose keyboard has nine columns of keys, only the first or lower five denominational orders are employed (1. e., if no larger than five-digit numbers are introduced into the adding machine), the present invention makes it possible to use the surplus or higher denominational orders and their printing mechanism to record symbol numbers, etc. without carrying such numbers into the accumulator. Nevertheless, the entire accumulator capacity of the machine may be employed in accumulating and recording totals and sub-totals. A further example is that disclosed in Basquin and Haegele Patent No. 2,131,683, wherein the lower denomina- 5 number of the miner to be credited for the load in the car. In batching apparatus wherein the ingredients comprising the batch are weighed, the surplus orders may be used to record a number symbol (representing the material weighed) opposite its weight. These illustrations will serve to suggest the fields of uses for the invention.

The invention is here embodied in a standard key-set adding machine of simple construction,

such as that disclosed in Barrett Patents Nos.

1,784,862, 1,811,840, 1,925,089, 1,935,609 and 1,949,446. As will be apparent, the invention is however, capable of embodiment in many other designs of adding machines and without necesitating substantial modification or alteration of the standard apparatus.

As illustrating one use of the present'addlng machine, the latter may be embodied in a weighing and recording apparatus such as that shown in said Patent No. 2,131,683. This is illustrated somewhat diagrammatically in Fig. 2 wherein the pertinent elements of the apparatus of said patent are diagrammatically represented as follows: ii is the dial shaft movable responsively to the load on the scale, on which shaft are fixed the conventional pointer 12 and the step cams l3, II o and I5. As explained in said patent, the latter step cam serves in conjunction with the step cam is to set the several digit slides for the lower five denominational orders of the adding machine. It

will be understood by a reference to said patent 5 that the dial shaft and step cams are rotated responsively to the load on the scale to a position representing the weight of the load on the scale. Further it will be understood that the step cams represent one means, equivalent to the keys on the adding machine keyboard, for setting the digit slides of the adding machine in position to carry the appropriate number on the type segment into printing position. It will be noted that the digit slides are equipped with extension fingers is which project from the adding machine and are provided with extremities which engage the several step cams.

The digit slides 2! representing the higher or surplus denominational orders are set in any desired way to bring the proper digits on the type segments into printing position. Such setting means may be the usual keys on the keyboard,

or, as here shown, a step cam 2!, which in this instance serves to record the tare weight on the scale. The digit slides 20 are also provided with extension fingers 22 which engage the several series of steps on the step cam 2|. If the digit slides be key-set, they need not be provided with the extensions 22.

Where, as here, the digit slides are set not by keys but by extensions on the digit slides themselves, it is not essential that the adding machine be provided with a keyboard (excepting totalizer and accessory keys), but the presence of the keyboard would not interfere with the operation of the apparatus. Where the surplus denominational orders are manually key-set, the machine should, of course, be provided with a keyboard covering all key-set orders.

As shown in Fig. 1, the adding machine is tilted from its normal position, so that the line of travel of the digit slides and their extensions intersect the axis of dial shaft H.

The aforesaid surplus denominational orders are made independent of the accumulator mechanism by relatively shifting the accumulator pinions 25 and their adding sectors or accumll1ator pinion driving racks 26 to non-meshing relationship, thereby allowing the adding sectors 28 and their type segments 21 to be moved independently of the accumulator and without carrying into the accumulator the digits recorded by these type segments. This is advantageously effected in the present construction by substituting for the usual accumulator pinions of the lower denominational orders, wider pinions 28 which allow the pinions 25 to be shifted laterally into and out of mesh with their adding sectors 2 without disturbing the normal intermeshing relation between the adding sectors 2! of the lower denominational orders and their pinions. This arrangement makes it posible to shift the accumulator shaft 3| laterally to mesh and unmesh pinions 25 and adding sectors 2| while maintaining the normal relation between pinions 28 and their adding sectors 2! (see Figs. 8 and 7).

While the illustrative accumulator mechanism is of a conventional type, it may be found illustrated and described in greater detail in said Barrett patents. For example, the accmnulator pinions 25 and sectors 26 herein correspond respectively to the accumulator pinions 26 and sectors 5 in Figs. 2 and 5 of said Barrett Patent No. 1,949,446, and to the pinions 108 and gear racks 107 in Figs. 2, 16, 17 and 18 of said Barrett Patent No. 1,811,840.

To use the higher denominational orders for independent recording purposes (not involving totalization), the accumulator shaft II is shifted laterally to unmesh accumulator pinions 2| and their adding sectors 26. Any record made by the digits on the type segments carried by sectors 20 does not, therefore, influence the total. On the other hand, the lower denominational orders represented by adding sectors 28 have their normal relation with the accumulator which sens to accumulate totals of numbers introduced by the lower denominational orders in the usual manner and to thefull capacity of the accumulator.

To record a total or sub-total it ordinarily requires the use of some or all of the higher denomlnational orders, making it necessary to em- 5 ploy the adding sectors 26 and their type segments. In that event, the accumulator shaft ii is shifted laterally to place sectors 28 in mesh with their pinions 25. The latter sectors are, therefore, controlled by the accumulator in the 10 usual way to print totals and subtotals.

An illustrative form of accumulator shifting mechanism is particularly illustrated in Figs. 6

to 8. As shown in Fig. 6, the pinions 2| and their sectors 20 are held in unmeshed relation by a slid- 15 able cam block I having a recess ll with an inclined cam surface leading therefrom. For the recording of totals and sub-totals, cam block II is shifted to bring its recess 36 into registry with accumulator shaft into which recess the latter is moved by flat spring 31, bringing pinions 2i and their sectors into mesh (see Fig. 7). Cam block I! is advantageously controlled by the total and sub-total keys II and 39 respectively. As here shown, (Fig. 8) the totalizer cam II is 25 moves the same in the direction of the arrow adjacent the pin (Fig. 8) to move notch it into registry with accumulator shaft 8| (Fig. 7), bringing about the intermeshing of pinions -2i and their sectors 2'. Thereupon the actuation of the adding machine operating lever 44 causes the accumulator to op- 35 crate the type segments to register the total accumulated therein and the printing mechanism to print such total on the tape or other record ll. To clarify illustration, (Fig. 8) the totalizer key lever and totalizer cam I have been more heavily shaded to bring out the train of mechanism by which the cam block I5 is operated as aforesaid. Sub-total lever II also similarly operates cam 4i and block 38.

Upon giving the operating handle 44 its return 45 movement (which is opposite that of the arrow on the handle), a pin 0 carried by the accumulator cam 41 (Figs. 6 and 8) engages slide ll connected to pin 43, moving the latter and cam block as (to the position shown in Fig. 6) to shift accumulator shaft and unmesh pinions 2i and sectors 28. 'Ihe accumulator cam 41 has been more lightly shaded to enable it to be clearly distinguished from totalizer cam ll (Fig. 8).

As shown in Fig. 10, earn block II is provided with forked and slotted ends 4! and II which straddle pins 82 and u by which the block is guided for sliding operation.

It will be understood that in the present type of adding machine. the only difference between subtotal operations and totalizing operations is that accumulator pinions instead of being restored to the position representing the accumulated total are cleared. The mechanism for shifting the accumulator and its pinions into and out of mesh with the adding sectors for the foregoing purposes is well known and need not be described.

To compensate for the lateral displacement or shifting of the accumulator pinions a, the final or carrying teeth I on the respective sectors 28 are increased in width so that they will engage the sectors in their normal operation of "carrying" from one accumulator pinion to the next. (See Figs. 4 and 5.) The manner of "carrying" from one accumulator pinion to the one of next higher denominational order is illustrated in greater detail in Fig. 2 of said Barrett Patent No. 1,949,446, in Fig. 3 of said Barrett Patent N0. 1,935,609, and in Fig. 16 of said Barrett Patent No. 1,811,840. Figs. 4 and 5 in the present application illustrate simply the details herein involved, other details having been omitted.

Ordinarily, the adding sectors prevent accidental shifting or displacement of the accumulating pinions. The unmeshed pinions 25 which are not thus held against accidental shifting are here shown provided with means which impose a slight friction or brake on the sectors and thereby prevent their accidental displacement. Such means are here shown in the form of flat leaf springs 55 which engage the edges of the pinion discs 56. Their sector of engagement with the discs 56 is made long enough to span the looking notches carried by each disc 56 to avoid catching in such notches.

In Fig. 9 is illustrated a specimen record tape or sheet wherein the digits in the first three surplus columns represent a tare weight or some other numbered symbol which is not carried into the total. It is desirable that the surplus digits be easily distinguishable from the others. Those for recording the tare are here distinguished by underlining and the last or highest column which may be employed for number symbols are distlnguished by subjacent dots. The means em ployed for distinguishing the non-adding from the adding digits may, of course, be greatly varied. The five lower denominational orders to the right represent the digits (in this case the net weight records) which are carried into the accumulator and thus totalized. The line of digits 51 represents a sub-total of the above five columns of digits and carries the customary symbol 58 (S in this case) to indicate a sub-total. The line of digits at 59 represents a total which is characterized by the symbol 6|. It will be noted that the digits in the totals and sub-totals may carry into the higher denominational orders in the ordinary way, i. e., the entire capacity of the accumulator and the printing segments are available for accumulating and printing totals and sub-totals. In most types of adding machines, the mechanism will accumulate and print a. total which may contain one more digit (in this case ten in all) than the number of banks of keys.

Obviously the invention is not limited to the details of the illustrative construction since these may be variously modified. Moreover, it is not indispensable that all features of the invention be used conjointly since various features may be used to advantage in different combinations and subcombinations.

Having described our invention, we claim:

1. In an adding machine the combination comprising an accumulator having pinions for the several denominational orders, accumulator pinion driving racks meshing with the respective pinions, a plurality of said pinions for the lower denominational orders being wider than those for the higher orders to permit said accumulator to be shifted longitudinally to unmesh the higher order pinions, the lower order pinions remaining in mesh, and means for shifting said accumulator to move said higher order pinions in and out of mesh with their driving racks.

2. In an adding machine, the combination comprising an accumulator having pinions for the several denominational orders, accumulator pinion driving racks whose faces mesh with those of the respective pinions, certain of the meshing faces between the racks and pinions for the lower denominational orders being wider than those for the higher orders to permit relative longitudinal shifting between the racks and pinions to unmesh those of the said higher orders while maintaining those for the lower orders in mesh, and means for eifecting relative shifting between said racks and pinions to mesh and unmesh those for the said higher orders.

3. In an adding machine, the combination comprising adding sectors for a series of denominational orders, an accumulator having corresponding accumulator pinions adapted to mesh with the respective sectors, means for relatively longitudinally shifting a higher order accumulator pinion and its adding sector to unmesh the same and for maintaining the lower order accumulator pinions and their adding sectors in normally meshing relationship, and means operable upon the taking of a total for temporarily effecting relative shifting between said higher order pinion and its sector longitudinally to restore meshing relationship in order to make the full capacity of the accumulator available for exhibiting a total.
